Navigating Modified Comparative Negligence: Recovering in 51% Bar States

Why the threshold matters more than the percentage

A subrogating carrier stands in its insured's shoes. Whatever fault a jury, an arbitration panel or an adverse carrier assigns to the insured comes off the recovery, and in a modified comparative negligence state it can wipe out the recovery entirely. The percentage reduction is the part everyone budgets for. The bar is the part that quietly closes files.

There are two versions of the bar. Under the 51% rule, the insured is barred only when its fault is greater than the fault it is compared against, so an even 50/50 split still recovers half the damages. Under the 50% rule, the insured is barred when its fault equals or exceeds the other side's, so the same 50/50 split recovers nothing. Same facts, same evidence, same paid loss, and a different result based only on where the loss happened.

For a subrogation director, that means a disputed-liability intersection file in Illinois and the identical file in Georgia should not be worked, reserved or settled the same way. One is a negotiation about price. The other is a negotiation about whether the claim exists.

Which states use which bar

The 51% bar states, where the insured still recovers at exactly 50% and is barred above it, include Connecticut, Delaware, Hawaii, Illinois (735 ILCS 5/2-1116), Indiana (Ind. Code 34-51-2-6), Iowa, Massachusetts, Minnesota (Minn. Stat. 604.01), Montana, Nevada, New Hampshire, New Jersey (N.J.S.A. 2A:15-5.1), Ohio (R.C. 2315.33), Oklahoma, Oregon, Pennsylvania (42 Pa.C.S. 7102), South Carolina, Texas (Tex. Civ. Prac. & Rem. Code 33.001), Vermont, West Virginia (since its 2015 move to modified comparative fault), Wisconsin (Wis. Stat. 895.045) and Wyoming.

Florida joined the group in 2023. House Bill 837 added Section 768.81(6), which bars any party found greater than 50 percent at fault for its own harm in negligence actions filed after the law took effect on March 24, 2023, with medical negligence excluded. Florida had applied pure comparative fault since Hoffman v. Jones in 1973, so older and newer Florida files can carry different math on the same facts.

The 50% bar states, where the insured is barred at 50% or more, are Arkansas, Colorado, Georgia (O.C.G.A. 51-12-33(g)), Idaho, Kansas, Maine, Nebraska, North Dakota, Tennessee (McIntyre v. Balentine, 1992) and Utah. Michigan is a hybrid: under MCL 600.2959, a party more than 50% at fault loses noneconomic damages but still recovers reduced economic damages, which is where property subrogation sits.

Around the edges are the pure comparative states (including California, New York, Washington and Missouri), the contributory negligence holdouts (Alabama, Maryland, North Carolina, Virginia and the District of Columbia) and South Dakota's slight-versus-gross comparison. Widely circulated charts disagree on Oklahoma and South Carolina, and some still list West Virginia under its pre-2015 rule. Read the statute or the controlling case before you close a file on a threshold argument.

Compared against whom: individual versus combined fault

The second question is what the insured's share is measured against. Wisconsin and Minnesota compare the insured's fault to each defendant separately. Wis. Stat. 895.045 measures the plaintiff's negligence separately against each person found causally negligent, and Minn. Stat. 604.01 allows recovery only if the plaintiff's fault was not greater than the fault of the person against whom recovery is sought. Pennsylvania, New Jersey and Texas compare the insured to the defendants combined, and Ohio and Indiana go further by counting nonparty fault in the comparison.

The difference shows up in multi-vehicle and construction losses. Take a Wisconsin chain collision where the insured is assigned 30%, a box truck 45% and a delivery van 25%. The insured recovers from the box truck, because 30% is less than 45%, but is barred against the van, because 30% is greater than 25%. Move the same verdict to Pennsylvania and the insured can recover against both, because 30% is well below the combined 70%. Joint and several rules then decide who actually writes the check: Wisconsin holds a defendant jointly and severally liable only at 51% or more, and Texas only above 50%.

Texas adds one more wrinkle. Chapter 33 lets defendants designate responsible third parties who are never sued, and the jury allocates fault to them too. The empty chair does not move the insured's 50% line, but it can push each named defendant's share below the level where joint and several liability applies, which shrinks what is collectible.

A worked example at the 50/50 line

CLM-24-118204 is a left-turn intersection collision. The insured, driving a 2021 Subaru Outback, entered on a stale yellow; the other driver, in a 2019 Ford F-150, turned left across the insured's path. The carrier paid $21,400 under collision coverage and the insured carries a $1,000 deductible, for a total subrogable loss of $22,400. One independent witness puts the insured slightly over the limit. The adverse carrier's opening position is 50/50.

If the loss happened in Illinois, a 50/50 allocation returns $11,200, shared with the insured to cover the deductible. If it happened in Georgia, a 50/50 allocation returns $0, because Georgia bars a party that is 50 percent or more responsible. Move the allocation to 45/55 in the insured's favor and both states pay 55%, or $12,320. In Georgia, that five-point swing is worth the whole recovery. In Illinois, it is worth $1,120.

In Virginia or Maryland, contributory negligence means any fault assigned to the insured bars the claim, so the file needs a clean liability story or it has no value. In New York or California, pure comparative fault means even a 70/30 allocation against the insured still returns 30%, or $6,720.

Where to spend evidence effort

Most subrogation units allocate investigation time by paid amount. In modified comparative states, it is more productive to allocate by distance from the bar. A $9,000 file sitting at a disputed 50/50 in a 50% bar state has more to gain from one more witness statement than a $40,000 file with an uncontested 90/10.

The evidence that moves allocations in the 40% to 60% band is usually already in the file or close to it: event data recorder downloads, telematics speed traces, signal timing records, intersection or dashcam video, the citation section of the police report and the recorded statements. Arbitration Forums panels apply the law of the state where the loss occurred, so a filing in a 50% bar state that rests on a soft 50/50 argument is a filing to reconsider before it goes in.

Negotiation posture should follow the rule too. In a 51% state, accepting 50/50 is a business decision about cost and cycle time. In a 50% state, accepting 50/50 is abandoning the claim, and the counteroffer has to be built around evidence that pulls the insured below the line.

How Ishqkala handles fault thresholds

The Ishqkala Liability Reasoning Engine tags every opportunity with the loss state's fault rule and comparison method, then estimates recovery across a range of plausible allocations instead of a single point. Files whose likely allocation sits within a few points of the bar are flagged so the subrogation professional sees them first, along with the specific facts in the notes and reports that support or weaken the insured's position.

That scoring feeds the same queue that tracks limitation dates, so a threshold file in Georgia with 60 days left does not sit behind a larger but safer file. The software ranks and explains. The recovery professional and counsel decide the allocation they will accept.
